AIR-INLET REGULATOR FOR CARBURETERS.

Relating to Air-Inlet Regulators for (larhu--- rcters, of which thefollowing is a specifica- This invention relates to an air inletregulater with automatic adjustment, for ad1nitting air to the mixingchamber of a carburetor. 1 1

The valve or regulator is chiefly characterized by the auton'iaticadjustment parts of the regulator, arranged in a nozzle or chamberconnected to the carhureter being constituted by two perforated disksapplied one above the other, and arranged slightly above the air inletopenings inade' in the admission nozzle; these disks are arrangei'irelatively to each other in such manner that the openings of onecorrespond to solid portions of. the

other and vice versa 'ihe disk arranged imn'iediately above theopeningsdn the adi'nission nozzle; with which openings coincide theopenings in the disk is fixed, While the second, upper disk, which isspring-cinitrolled,

exact manner above thc i'irst one, under the action ol tic suctionproduced in the carbureting chambe so as to rise to a greater or lesserextent ahovcthe other, according to the magnitude of the suction, and touncover entirely the openings of the latter disk, while remaining; atecertain distance above them. The VOlUtDG of air thus admitted, with theinlet openings of the-fined disk entirely open,

by the area of the airpassage formed between the two disks, saidvaryingmom-ding to the degree of elevation of the niovahlcdisl;corresponljling to the suc tion in the carhureting chamber.

The air admission nozzle is preferably of a truncated cone shape,widening; at the base, so that it and the disks arranged within it canhe of suliicient diameter to make the total area of their orifices forthe passage of air, corresprnid to that of the air inlet opening to thecarlirureting ,chainher.

The whole and the details of the device according to this invention areclearly shown in the accompanying drawing.

- As will he seen from the drawings, the car hurcting chamber (L isconnected to a truncated cone nozzle l), having a widened lease closedby a cap or plate 6 screwed on to it,

and provided with air inlet openings (2.,

'lln'ough the-plate 0 passes, in the center, a

rod a secured at its-upper end to a spider .i'n rotor a, 'said rod 6niitfand a lock-nut {/fto fix/the nozzle b-to the carliiureting chamber(1. a little above the cap 0, is arranged'a fixed disk It provided withradiating or other openings i separated by full intervals j, Above thisdisk is arranged another similar disk [0 in such manner that, itsopenings- 6 ci'n'r'espondto the hill spaces y, and its'iull spaces m toA the openings 46 in the disk 7t, and vice versa.

Throu gh the center (ii-the two disks his passes in its movement awayfrom and nearer to the disk it; a small rod pscCured-tc) the disk 7;,and passing through a corresponding opening Z in the disk 1: completingthis guidance and preventing thedisk from turningrelatively to thedisi'c'it. A spring n is also arranged on rod efahove the in ovahle disklit, on which it acts W1Ch a tendency the disk it. /Vith thisarrangement it will be seen that, when the very smallest suction takesplace in the carhuretingchainher a, and

consequently in the nozzle b forming continuation of it, whichdepression, must be sulhcient to overcome the Weak resistance of In thenozzle b,

the rode which acts as a guide for the disk It" to apply it against thespring It and the weight of'the movable disk icthe latter wil be drawnaway from the disk It to a distance corresponding to the suction exertedcompletely uncovering. the

orinees i through which air will pass through their full area, but arealimited by the listance between the disks 7t and 7c and finally throughthe open ings Z of the disk it, through the full area of the latter, andwill eii'iter the carhureting chamber it through the nozzle 1).

When the suction in the carhureting eha1nher a L-llCi in the nozzle 1)ceases the disk It will be applied by the spring a against the disk It,the respective air inlet 0 enings i Z of the two disks, thus becoming cosedr by the correthen will pass through the sponding full spaces lm. Inthis way the adm1ss1on of air to the carburetlng chamber a will beautomatically regulated in exact acthe air admitted.

In order to allow the total, area for the admission ofair in thenozzle 1) to be 'at least equal, and preferably superior, to that of theair inlet in the carbureting chamber a, the .nozzle is widened at thebase corresponding to the size of the cap 0 and disks hand is so thatthe number and the cross-sectional area of the orifices d, i and l'ofthe cap and disks respectively shall ive for each of those parts,

'a total area for t e passage of air, at least equal to or even greaterthan the area of the inlet to the carbureting chamber a.

What 'I claim as my invention and desire to secure by Letters Patentis- 1. In an automatic air inlet regulator for carbureters thecombination with a casing, a perforated cover closing one end of saidcasmg, and a perforated fixed disk in said casing and parallel andadjacent to said cover, of a correspondingly perforated nonrotatabledisk of a diameter equal to that of the interior of the casing andseated directly upon and parallel but relatively movable to said fixeddisk, the solid portions of the movable disk :as setforth.

1 covering and closing the perforations of the fixed disk and viceversa, a spring for pressing the movable disk upon thefixed disk,meansfor preventing lateral motion of the movable disk relatively to thefixed disk and a suction pipe connection between the casing and themotor, so that the uantity of air which penetrates is regulated by thesuction of the motor acting on the upper surface of the movable disk toseparate the two disks more or less from each other, substantially asset forth.

2. An automatic air inlet regulator for carbureters comprising a casing12, the perforated base 0 thereof, a perforated disk'h fixedly mountedbetween the base and the end of the casing, a vertically movablenon-rotatable perforated suction disk k, means for applying it directlyagainst the fixed disk,'and means for guiding it in its verticalmovement, and a suction pipe connection between the'casing and themotor, so that the uantityof air which penetrates is regulated y thesuction of the motor acting on the upper surface ofthe movable disk toseparate-the two disks more or less from each other, substantially Intestimony whereof I have signed ,my name to this specification in thepresence of two subscribing witnesses. v
